Voy Por Ustedes, winner of the Queen Mother Champion Chase for Alan King, has joined Nicky Henderson in a shock move.

King saddled the Sir Robert Ogden-owned gelding to victory in the Cheltenham two-miler four years ago - 12 months after he landed the meeting's Arkle Trophy. But, after disappointing last season, the 10-year-old was found by Ogden's vets to be suffering from a fractured hip bone.

"Sir Robert felt a fresh initiative would be beneficial to the horse and he has joined Nicky Henderson at Seven Barrows," Ogden's racing manager, Barry Simpson, said yesterday.

"He does not hold any entries for the Cheltenham Festival, but will be aimed towards Aintree, Punchestown and Fairyhouse." Meanwhile, Noel Meade yesterday revealed Lexus Chase hero Pandorama is no better than "50-50" to make the Cheltenham Gold Cup line-up on March 18 after suffering an injury.
